在单个查询中从mongo中删除多个文档 [英] Remove multiple documents from mongo in a single query

问题描述

我有一个要删除的mongo'_id'列表.目前我正在这样做

I have a list of mongo '_id' which I want to delete. Currently I am doing this

# inactive_users -->  list of inactive users 
for item in inactive_users:
    db.users.remove({'_id' : item})

但是我的问题是列表太大...(可能超过100,000个).因此，查询列表中的每个项目只会增加服务器的负载.是他们在mongo查询中传递整个列表的一种方法，这样我就不必一次又一次地触发查询.

but my problem is the list is too huge... (it might go 100,000 +). So querying for every item in list will only increase the load on server. Is their a way to pass the entire list in mongo query so that I dont have to fire query again and again.

谢谢

推荐答案

db.users.remove({'_id':{'$in':inactive_users}})
